VNC without access to set up port forwarding

I just bought the VNC Viewer app for my iPhone 4 and got it to work over 3G and wifi with my macbook pro connected to my home network. I know very little about networking but I knew enough to be able to set up port forwarding to my ip on my router at home. The problem is that I am a student in college right now, so my computer will be hooked up to the schools network when winter break is over. I have no access to set anything up on the network at school, so how will I get this to work? I made a host name at no-ip (does that allow me to connect to my computer even when my ip changes?), and I read something about being able to set up an ssh tunnel to make it work...maybe? I now have no idea what to do and the other forums I've read about this topic are using language that I am not familiar with. I need some network education! Again, the problem is setting up my MacBook Pro to allow a VNC connection on a network I have no control over. Thanks!
